CMake生成Xcode失败 No CMAKE_C_COMPILER could be found

在cmake生成Xcode项目时报错“No CMAKE_C_COMPILER could be found”

原因是在命令行中xcode–select指向的是/Library/Developer/CommandLineTools，生成xcode项目时，需要将xcode–select指向/Applications/Xcode.app/Contents/Developer

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

如果设置xcode–select之后仍旧报错“No CMAKE_C_COMPILER could be found”, 解决方案是:

cmake ../ -GXcode -DCMAKE_C_COMPILER="$(xcrun -find cc)" -DCMAKE_CXX_COMPILER="$(xcrun -find c++)"

如果CMake的输出log中提示下面错误时, 可以通过升级CMake版本来解决

“error: An empty identity is not valid when signing a binary for the product type ‘Command–line Tool’. (in target ‘CompilerIdCXX’ from project ‘CompilerIdCXX’)”
