Description of defect
Follow up from #12837
I am trying to create two binaries from a single repo using the new CMake build system but not having much sucess. I have setup a root CMakeLists.txt which creates a base library target which depends on the mbed-os build sources and adds some common project sources. In two folders I have a CMakeLists.txt which adds an executeable and additional target specific source files.
When building I either get multiple copies of mbed-os (instead of a single build follow by linking for each executable) or a get errors about multiple definitions / symbols.
I'm fairly new to CMake-based projects so this might just be user error, but I'm not sure what the right definitions are. Additionally I get the following error:
CMake Error: Files to be generated by multiple different commands: "{project}/cmake-build-debug/compile_time_defs.txt"
The project structure looks like the following:
root
|-> mbed-os
|-> common
| |-> include
| |-> src
|-> foo
| |-> CMakeLists.txt
| |-> main.cpp
|-> bar
| |-> CMakeLists.txt
| |-> main.cpp
|-> CMakeLists.txt
|-> mbed-lib.json
The root CMakeLists.txt

set(MBED_PATH ${CMAKE_CURRENT_SOURCE_DIR}/mbed-os CACHE INTERNAL "")
set(MBED_CONFIG_PATH ${CMAKE_CURRENT_SOURCE_DIR}/.mbedbuild CACHE INTERNAL "")
