SOURCE_DIR is defined when compiling the *.cc file of a test [1]. For
example, if you have the test layout
my_test.cc
my_test.output
and you call DEAL_II_PICKUP_TESTS() in that subdirectory. In that case
the my_test.cc file will be compiled with a compiler flag similar to
-DSOURCE_DIR=${CMAKE_CURRENT_SOURCE_DIR}
It is not available in any other compilation unit (i.e. *.cc file). Or
for the second class of tests where you specify a *.prm file [2].
Best,

[1] The SOURCE_DIR preprocessor definition is set up in line 266 of the
macro cmake/macros/macro_deal_ii_add_test.cmake.
[2] In this case a test gets the full path to the parameter file as
first argument. So simply stripping of the filename should be enough to
get the source directory of the tests.
