If the two "version" are needed you may build them in a single build.

add_library(libv1 ${LIB_SRC})

add_library(libv2 ${LIB_SRC})
set_target_properties(libv2 PROPERTIES COMPILE_FLAGS "-DV2")

add_executable(t1 t1.c)
target_link_libraries(t1 libv1)
add_executable(t2 t2.c)
target_link_libraries(t2 libv2)
add_executable(t3 t3.c)
target_link_libraries(t3 libv1 libv2)

so that in the same build you have the 2 versions you can directly use
with add_test.

add_test(Test1 t1)
add_test(Test2 t2)
add_test(Test3 t3)

but may be I'm missing something about your "2 versions"?

Alternatively, may be you can decide that your needed
"temporary" install will always be in a fixed location relative to the
build tree:

${CMAKE_BINARY_DIR}/tempinstall/
then you always know where are installed the lib, executable etc...
