Update the IAR linker and archiver rules to use the `<CMAKE_LINKER>`
and `<CMAKE_AR>` placeholders instead of hard-coding the tool names.
Fixes: #22395
This was previously fixed by commit d46590910c (Check*CompilerFlag: Do
not set result as a normal variable too, 2020-09-21, v3.18.3~1^2^2), but
was regressed by refactoring in commit 90dead024c (CheckCompilerFlag:
unified way to check compiler flags per language, 2020-09-25,
v3.19.0-rc1~88^2) due to the changes being developed concurrently.
Fix it again, and add a test case.
Fixes: #21207
In commit a90d2a9eed (IntelLLVM: Add support for Intel LLVM-based
compilers, 2020-11-02, v3.20.0-rc1~89^2~20) we accidentally left out
activation of the C/C++ standard level selection logic when IntelLLVM is
targeting the MSVC ABI.
Fixes: #22388
Update the change from commit c6aaaf066a (DetermineCompiler: Restore
identification of MSVC with no INCLUDE dirs, 2021-06-29,
v3.21.0-rc2~6^2) to also work with no `LIB` dirs. Add the `-c` flag to
compile an object file without linking.
Since commit bd844387df (ROCMClang: Add the ROCm toolkit derived clang
compiler to CMake, 2020-08-28, v3.21.0-rc1~66^2~6), our generated
compiler id source file contains a preprocessor condition of the form
#elif ... && __has_include(...)
When MSVC is invoked with no include directories in the `INCLUDE`
environment variable or in `-I` flags, its implementation of
`__has_include` errors out immediately. This breaks identification of
the compiler.
Work around the problem by adding a fallback attempt to compile the
identification source using a dummy include directory.
RPM 4.11.3 for el7 contains backported support for the RPM weak dep tags.
It only supports querying those tags, but rpmbuild can not make use of them.
Since CPack relies on rpmbuild --querytags to check for support, this
commit switches to rpm --suggests to check for support of weak
dependencies.
Fixes: #22350
In 3aec26660a (Merge topic 'nasm_add_deps', 2021-03-03) the
ASM_NASM language enabled the generation of GCC compatible
depfiles for NASM. Unfortunatly, those are not supported by YASM.
Fixes: #22341
In 5e941a545b (ExternalProject: Ensure git fetch if updating to hash we
don't have yet, 2021-05-09), the form ${ref}^{commit} was used to ensure
the ref was treated as a commit. When running under a MSYS2 or
Cygwin shell, the {commit} part can be translated by the shell, leaving it as
${ref}^commit, which git doesn't understand. Use the equivalent but
safer form ${ref}^0, since it won't be subject to the shell substitution
issue.
Fixes: #22299
If a project or user sets a variable or cache entry named `C`, `CXX`,
`CUDA`, `Fortran`, `CSharp`, or `ISPC`, we were previously comparing
each enabled language name to the value of that variable, rather than
the name itself. Double-quote the string to take advantage of policy
`CMP0054`, but also add "x" prefixes to support projects that do not set
the policy.
This extends a similar fix in commit bd16a985fc (CompilerId/Features:
Tolerate variables named for languages, 2021-04-28) in more places. In
particular, ensure that we consider the proper list of compiler ids.
Issue: #22125
I've noticed the default installer for MikTex does not prompt for
escalation. So, many installations I find do not have registry entries.
This should cover finding it in the current defaults.
Since commit 20ab504591 (FindBLAS: Do not statically link against iomp5
in the case of Intel MKL, 2021-04-11), we no longer find MKL's BLAS when
using the GNU compiler because FindOpenMP chooses libgomp instead of
libiomp5, and mkl_intel_thread depends on the latter. Revert the change
for now. A new approach will be needed to solve the original problem.
