From 2aecffe0f0e14f3ef635e8cd7b405420f2385de2 Mon Sep 17 00:00:00 2001 From: Lasse Collin Date: Sun, 16 Jun 2024 19:37:36 +0300 Subject: [PATCH] CMake: Use CMAKE_THREAD_LIBS_INIT in liblzma.pc only with pthreads This shouldn't make much difference in practice as on Windows no flags are needed anyway and unitialized variable (when threading is disabled) expands to empty. But it's clearer this way. --- CMakeLists.txt | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index d77d5fd0..ff34acdb 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -1428,7 +1428,13 @@ else() set(includedir "${CMAKE_INSTALL_FULL_INCLUDEDIR}") endif() -set(PTHREAD_CFLAGS "${CMAKE_THREAD_LIBS_INIT}") +# Threads::Threads is linked in only when using POSIX threads. +# Use an empty value if using Windows threads or if threading is disabled. +set(PTHREAD_CFLAGS) +if(USE_POSIX_THREADS) + set(PTHREAD_CFLAGS "${CMAKE_THREAD_LIBS_INIT}") +endif() + configure_file(src/liblzma/liblzma.pc.in liblzma.pc @ONLY) # Install the library binary.
