Intel MPI on Windows prefixes all outputs with some boilerplate
copyright text. By discarding it, we should prevent any potential
clashes with our regex parsing.
Intel MPI has an optional feature to check compatibility with the
compiler, given by I_MPI_CHECK_COMPILER.
This commit adds support for executing that check.
For MPICH derivates and Intel MPI, we can improve the compiler wrapper
behavior and accuracy by defining certain environment variables if they
haven't been set otherwise.
If our ``find_library`` step hasn't used a particular link directory at
all, it's best to retain it in order to prevent issues from secondary
dependencies not being found.
This replaces hardcoded expectations of flags like -l and -L with a
dynamical solution based on CMake platform variables.
Furthermore, the linker flag parsing is dynamified to support more forms
and given linker paths are now removed properly from the linker flags.
The parsing of link information coming from the compiler wrapper has been improved:
- Support MSVC /link argument separation properly and add support for potential VC++ link flags
- Rely on the global import/static/shared library suffixes instead of hardcoded special values.
This should improve compatibility with Cygwin and MinGW should any MPI implementation there need this behavior.
- Don't use ``find_library`` if the full path of a library is known anyways.
This introduces concurrent thread processing in the `_autogen`
target wich processes AUTOMOC and AUTOUIC.
Source file parsing is distributed among the threads by
using a job queue from which the threads pull new parse jobs.
Each thread might start an independent ``moc`` or ``uic`` process.
Altogether this roughly speeds up the AUTOMOC and AUTOUIC build
process by the number of physical CPUs on the host system.
The exact number of threads to start in the `_autogen` target
is controlled by the new AUTOGEN_PARALLEL target property which
is initialized by the new CMAKE_AUTOGEN_PARALLEL variable.
If AUTOGEN_PARALLEL is empty or unset (which is the default)
the thread count is set to the number of physical CPUs on
the host system.
The AUTOMOC/AUTOUIC generator and the AUTORCC generator are
refactored to use a libuv loop internally.
Closes#17422.
The libuv documentation states that the stream read callback may
be called with `nread == 0` for EAGAIN. Handle this gracefully.
It also states that the callee is responsible for closing the
stream on error. Always close the stream for `nread < 0`.
`FindDoxygen` already searches in hard-coded `/Applications/Doxygen.app`
directories. Search in the `Utilities` subdirectory too in case users
choose to put doxygen there.
Building Tcl with `makefile.vc` produces library files with a `t`
suffix to indicate threading support. Since threading support is
on by default in 8.6 anyway, the libraries should be compatible.
