Hi, there is also a variation based on the workaround given by David:

suppose you want to call:
bar_${foo1}(arg1 arg2)
bar_${foo2}(arg1 arg2)

you can create 2 files:
- bar1.cmake
macro(bar)
...
endmacro()

- bar2.cmake
macro(bar)
...
endmacro()

After that you can replace:
bar_${foo1}(arg1 arg2)
bar_${foo2}(arg1 arg2)
by:
include(${foo1}.cmake)
bar(...)
include(${foo2}.cmake)
bar(...)

where:
${foo1} = bar1
${foo2} = bar2

Damien R.
