Hi. This commit seems to have broken the following cmake command, on Windows
(with HEAD pointing at 76cad51ba700233d6e3492eddcbb466b6adbc2eb
<https://reviews.llvm.org/rG76cad51ba700233d6e3492eddcbb466b6adbc2eb>):
cmake -DLLVM_ENABLE_PROJECTS=clang -DLLVM_EXPORT_SYMBOLS_FOR_PLUGINS=ON
..\llvm-project\llvm
The symptom is the same as @cristian.adam shows above:
-- SampleAnalyzerPlugin ignored -- Loadable modules not supported on this
platform.
CMake Error at [...]/llvm-project/clang/cmake/modules/AddClang.cmake:185
(target_link_libraries):
Utility target "SampleAnalyzerPlugin" must not be used as the target of a
target_link_libraries call.
Call Stack (most recent call first):
[...]/llvm-project/clang/lib/Analysis/plugins/SampleAnalyzer/CMakeLists.txt:8
(clang_target_link_libraries)
With HEAD pointing at the previous commit,
`clang/lib/Analysis/plugins/CMakeLists.txt` does not add the `SampleAnalyzer`
subdirectory at all, because `LLVM_ENABLE_PLUGINS` has the value `OFF`. But
`CLANG_PLUGIN_SUPPORT` is `ON`, so now it does, and the above error happens.
If I try to work around this by setting `CLANG_PLUGIN_SUPPORT` to `OFF` as well
...
cmake -DLLVM_ENABLE_PROJECTS=clang -DLLVM_EXPORT_SYMBOLS_FOR_PLUGINS=ON
-DCLANG_PLUGIN_SUPPORT=OFF ..\llvm-project\llvm
... then this error happens instead:
CMake Error at cmake/modules/AddLLVM.cmake:676 (target_link_libraries):
Target "clang" of type EXECUTABLE may not be linked into another target.
One may link only to INTERFACE, OBJECT, STATIC or SHARED libraries, or to
executables with the ENABLE_EXPORTS property set.
Call Stack (most recent call first):
cmake/modules/AddLLVM.cmake:808 (llvm_add_library)
[...]/llvm-project/clang/examples/PrintFunctionNames/CMakeLists.txt:12
(add_llvm_library)
So, either way, the build fails.
