Subject: [PATCH] [CMake] Fix pthread handling for out-of-tree builds
|
|
|
|
LLVM defines `PTHREAD_LIB` which is used by AddLLVM.cmake and various projects
|
|
to correctly link the threading library when needed. Unfortunately
|
|
`PTHREAD_LIB` is defined by LLVM's `config-ix.cmake` file which isn't installed
|
|
and therefore can't be used when configuring out-of-tree builds. This causes
|
|
such builds to fail since `pthread` isn't being correctly linked.
|
|
|
|
This patch attempts to fix that problem by renaming and exporting
|
|
`LLVM_PTHREAD_LIB` as part of`LLVMConfig.cmake`. I renamed `PTHREAD_LIB`
|
|
because It seemed likely to cause collisions with downstream users of
|
|
`LLVMConfig.cmake`.
