1. libClangDriver.a shipped by MSYS2 needs -lversion which is not included in CMAKE_CXX_STANDARD_LIBRARIES by default. 2. Use string literal for DEFAULT_RESOURCE_DIRECTORY to support backslashes in path.

# FindClang
|
|
# ---------
|
|
#
|
|
# Find Clang and LLVM libraries required by ccls
|
|
#
|
|
# Results are reported in the following variables::
|
|
#
|
|
# Clang_FOUND - True if headers and requested libraries were found
|
|
# Clang_EXECUTABLE - Clang executable
|
|
# Clang_RESOURCE_DIR - Clang resource directory
|
|
# Clang_VERSION - Clang version as reported by Clang executable
|
|
#
|
|
# The following :prop_tgt:`IMPORTED` targets are also defined::
|
|
#
|
|
# Clang::Clang - Target for all required Clang libraries and headers
|
|
#
|
|
# This module reads hints about which libraries to look for and where to find
|
|
# them from the following variables::
|
|
#
|
|
# CLANG_ROOT - If set, only look for Clang components in CLANG_ROOT
|
|
#
|
|
# Example to link against Clang target::
|
|
#
|
|
# target_link_libraries(<target> PRIVATE Clang::Clang)
|
|
|
