Ok, interestingly that had no effect, but if I moved the
set(CMAKE_EXECUTABLE_SUFFIX_<LANG>) to the main CMakeFiles.txt file below
the project() call it worked.
On Fedora, when I commented out the include for the toolchain file and
applied it on the command line I ran into an issue where it seems like
cmake doesn't understand the source directory as it no longer looked in the
right place for the linker script. In the toolchain file it's set to a
sub-directory of the source dir but it's looking in the binary dir:
set(CMAKE_EXE_LINKER_FLAGS "-T${CMAKE_SOURCE_DIR}/stm32_flash.ld")
Output:
Linking C executable cmTC_51be3.elf
/usr/bin/cmake -E cmake_link_script CMakeFiles/cmTC_51be3.dir/link.txt

The build dir is the binary directory, not the source directory...
Thanks,
Richard
