try_compile: Escape CMAKE_<lang>_FLAGS in test projects (#14268) If CMAKE_<lang>_FLAGS contains quotes or other CMake language characters they must be escaped when written into the generated CMakeLists.txt file so that the test project parses them properly. Teach the TryCompile test to cover this case by adding a flag with quotes into CMAKE_C_FLAGS during a C language try_compile.

Handle targets in the LINK_LIBRARIES of try_compile. Imported targets are re-exported so that they can be used by the try_compile generated code with target_link_libraries. This makes the use of the cmake_expand_imported_targets macro obsolete. The macro is not able to expand the generator expressions which may appear in the IMPORTED_LINK_INTERFACE_LIBRARIES content. Instead it just sees them as 'not a target'.

Handle targets in the LINK_LIBRARIES of try_compile. Imported targets are re-exported so that they can be used by the try_compile generated code with target_link_libraries. This makes the use of the cmake_expand_imported_targets macro obsolete. The macro is not able to expand the generator expressions which may appear in the IMPORTED_LINK_INTERFACE_LIBRARIES content. Instead it just sees them as 'not a target'.

Generate modern-style cmake code. The commits 9db31162 (Remove CMake-language block-end command arguments, 2012-08-13) and 77543bde (Convert CMake-language commands to lower case, 2012-08-13) changed most cmake code to use lowercase commands and no parameters in termination commands. However, those changes excluded cmake code generated in c++ by cmake. Make a similar style change to code generated by cmake.

try_compile: Refactor argument processing Process all arguments in a single loop using a simple state machine. While at it, fix some error message typos. Also allow LINK_LIBRARIES with no actual libraries to disable use of the -DLINK_LIBRARIES=... from the CMAKE_FLAGS. This was already possible in the old logic if LINK_LIBRARIES was immediately followed by another keyword argument instead of the end of the argument list, so allow it in general. Update the RunCMake.try_compile test cases accordingly.

Allow toolchain files to specify an external toolchain. Clang can compile code, but uses the gcc tools for other tasks such as linking.

Refactor generation of shared library flags CMAKE_SHARED_LIBRARY_<lang>_FLAGS has flags on various platforms for a variety of purposes that are correlated with shared libraries but not exclusive to them. Refactor generation of these flags to use new purpose-specific platform variables CMAKE_<lang>_COMPILE_OPTIONS_DLL CMAKE_<lang>_COMPILE_OPTIONS_PIC CMAKE_<lang>_COMPILE_OPTIONS_PIE Activate the DLL flags specifically for shared libraries. Add a new POSITION_INDEPENDENT_CODE target property to activate PIC/PIE flags, and default to true for shared libraries to preserve default behavior. Initialize the new property from CMAKE_POSITION_INDEPENDENT_CODE to allow easy global configuration in projects. Although the default behavior is unchanged by this refactoring, the new approach ignores CMAKE_SHARED_LIBRARY_<lang>_FLAGS completely. We must leave it set in case projects reference the value. Furthermore, if a project modifies CMAKE_SHARED_LIBRARY_<lang>_FLAGS it expects the new value to be used. Add policy CMP0018 to handle compatibility with projects that modify this platform variable. Add a PositionIndependentCode test on platforms where we can get meaningful results.

try_compile: Add COPY_FILE_ERROR option to capture failure When the COPY_FILE operation fails optionally capture the error message with a COPY_FILE_ERROR option instead of reporting the error immediately. This gives callers a chance to do something else or report the error. Teach the RunCMake.try_compile test to cover bad argument combinations involving COPY_FILE_ERROR. Teach the TryCompile test to cover the case of a COPY_FILE error message captured by COPY_FILE_ERROR.

Fix try_compile RemoveFile anti-virus loop (#11503) Commit 3827991e (...fix...not being able to remove try compile code, 2008-03-26) introduced a loop of RemoveFile attempts to overcome anti-virus locks on recently created try_compile executables. Fix the logic in this loop to work when the file is already missing.
