Hi, I have a tool-chain file, which requires a variable to be set to the path to the compiler on the local machine:
set(CMAKE_C_COMPILER ${ARM_GCC_TOOL_PATH}/bin/arm-none-eabi-gcc)
set(CMAKE_CXX_COMPILER ${ARM_GCC_TOOL_PATH}/bin/arm-none-eabi-g++)
Now I want to give the user an error message, in case that this variable is not
set. The „usual“ check for the existence of the variable doesn’t work, because
the tool-chain file is included in different context, without access to the
cache.
Any idea?
regards,
Torsten
