Generator expressions are supported in many places and are a distinct concept worthy of their own manual page. The old builtin documentation was previously represented by preprocessor macros to generate it into each place that supports them. Factor out the duplicate content into a dedicated cmake-generator-expressions manual page and reference it from each original location.

add_test
|
|
--------
|
|
|
|
Add a test to the project with the specified arguments.
|
|
|
|
::
|
|
|
|
add_test(testname Exename arg1 arg2 ... )
|
|
|
|
If the ENABLE_TESTING command has been run, this command adds a test
|
|
target to the current directory. If ENABLE_TESTING has not been run,
|
|
this command does nothing. The tests are run by the testing subsystem
|
|
by executing Exename with the specified arguments. Exename can be
|
|
either an executable built by this project or an arbitrary executable
|
|
on the system (like tclsh). The test will be run with the current
|
|
working directory set to the CMakeList.txt files corresponding
|
|
directory in the binary tree. Tests added using this signature do not
|
|
support generator expressions.
|
|
|
|
|
|
|
|
::
|
|
|
|
add_test(NAME <name> [CONFIGURATIONS [Debug|Release|...]]
|
|
[WORKING_DIRECTORY dir]
|
|
COMMAND <command> [arg1 [arg2 ...]])
|
|
|
|
Add a test called <name>. The test name may not contain spaces,
|
|
quotes, or other characters special in CMake syntax. If COMMAND
|
|
specifies an executable target (created by add_executable) it will
|
|
automatically be replaced by the location of the executable created at
|
|
build time. If a CONFIGURATIONS option is given then the test will be
|
|
executed only when testing under one of the named configurations. If
|
|
a WORKING_DIRECTORY option is given then the test will be executed in
|
|
the given directory.
|
|
|
|
Arguments after COMMAND may use "generator expressions" with the syntax
|
|
"$<...>". See the :manual:`cmake-generator-expressions(7)` manual for
|
|
available expressions.
|
|
|
|
Note that tgt is not added as a dependency of the target this
|
|
expression is evaluated on.
|
|
|
|
::
|
|
|
|
$<TARGET_POLICY:pol> = '1' if the policy was NEW when the 'head' target was created, else '0'. If the policy was not set, the warning message for the policy will be emitted. This generator expression only works for a subset of policies.
|
|
$<INSTALL_PREFIX> = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.
|
|
|
|
Boolean expressions:
|
|
|
|
::
|
|
|
|
$<AND:?[,?]...> = '1' if all '?' are '1', else '0'
|
|
$<OR:?[,?]...> = '0' if all '?' are '0', else '1'
|
|
$<NOT:?> = '0' if '?' is '1', else '1'
|
|
|
|
where '?' is always either '0' or '1'.
|
|
|
|
Example usage:
|
|
|
|
::
|
|
|
|
add_test(NAME mytest
|
|
COMMAND testDriver --config $<CONFIGURATION>
|
|
--exe $<TARGET_FILE:myexe>)
|
|
|
|
This creates a test "mytest" whose command runs a testDriver tool
|
|
passing the configuration name and the full path to the executable
|
|
file produced by target "myexe".
