[Cmake] multiple compile of an object

[Andy Cedilnik]

Hi Ken,

You can always write a macro that writes a file and creates executable.
For example, let say you have several classes per library. You would do
something like this:

MACRO(CREATE_TEST classname libname)
  STRING(ASCII 35 POUND)
  WRITE_FILE("${CMAKE_CURRENT_BINARY_DIR}/test_${classname}.cxx"
    "${POUND}define ${classname}_MAIN_NEEDED\n${POUND}include
<${CLASSNAME}.h>")
  ADD_EXECUTABLE(test_${classname}
    "${CMAKE_CURRENT_BINARY_DIR}/test_${classname}.cxx")
  TARGET_LINK_LIBRARIES(test_${classname} ${libname})
ENDMACRO(CREATE_TEST)

Sounds good?

Then you just do:

CREATE_TEST(class1 mylib1)
CREATE_TEST(class2 mylib1)
CREATE_TEST(class3 mylib2)
