#Cmake, multiple toolchains, howto simple switch

[Mário Oravec]

Hi Leon,

so far I am using the following workaround

in top level CMakeList.txt I put the following targets which are created 
for both configurations and right click and build on particular target
does what I want. But would be more beautiful to have some support
in kdevelop

add_custom_target($test-host
                  WORKING_DIRECTORY top/build/host
                  # it builds tests
                  COMMAND make 
                 # it runs tests
                  COMMAND ./src/test/sb_peripheral_test
                  COMMENT building tests
                  )

add_custom_target(app-arm
                  WORKING_DIRECTORY top/build/app
                  # it builds app for arm
                  COMMAND make
                  COMMENT building target
                  )

You mean if you set launch and changes configuration let say to target
the correct launch is not preset as prefered? so you will have to again
choose it from menu?
