CMake cross-compiling: C flags from toolchain file ignored

Question

I use cmake for cross compiling. In my toolchain file there is a line

SET(CMAKE_C_FLAGS \"-std=gnu99\")

This variable is not set in CMakeLi

Answer 1

I've found a temporary solution by replacing the line

SET(CMAKE_C_FLAGS "-std=gnu99")

by

SET(CMAKE_C_FLAGS "-std=gnu99" CACHE STRING "" FORCE)
