Ideally, I want to be able to inject a message before any target actions are taken and possibly after. What I’m trying to achieve is only have those messages printed during≈ “make check” and “make test”, etc. > Now what happens is that the CHECK message is printed … during cmake(!). > message(“different note about TEST target…”) > message(“special note about CHECK target…”) Snippet in question in a top-level CMakeLists.txt file looks like this: I found that the IF statement has a TARGET keyword that should truthfully match for a particular build target, but it doesn’t seem to be working at least the way I’m trying to use it and would expect it to work. > I’m trying to print a message for a particular build target and am a bit stuck. > On 11/24/15, 12:04 AM, "CMake on behalf of Christopher Sean Morrison" wrote: Maybe you can use “add_custom_target” to create targets which do nothing but print the desired message, and then use “add_dependencies” to tie these targets back to your original ones?

In all, it’s working, but hopefully this info might be useful to any archive searcher hitting a similar problem… at least until is addressed. Made the test still run the ‘false’ message target too (via COMMAND cmake …), so it ends up in the testing log during make test and conveniently pauses for 3-4 seconds on just that one test (apparently the overhead on our build system to simply invoke cmake). What I ended up doing was punting on displaying the fancy message and just added a test whose test name was a very shortened form of the message intended (via add_test(NAME “NOTE\\ important\\ message\\ here”…). However, every which way I tried to invoke that target via add_test seemed to only produce an infinite loop during “make test” or ctest. I could create a custom target that only printed a message and ran ‘false’ to give an error and I could create another cmake target that ran ctest with -output-on-failure to see the message - and that worked just fine for running that target via cmake. I even tried to trick ctest by creating a test that printed a message but failed. Getting similar behavior for the “test" target seems to be impossible, though. I ended up adding COMMAND $ -E echo “…” lines to the add_custom_target() and that did the trick for my “check” target.
#Cmake print generator#
What threw me off, I think, was having "TARGET test” not actually pass and misunderstanding the docs that this would embed logic in the generator output. Makes sense for “if (TARGET…)” to truthfully enter if that target name exists. Thanks, that worked for printing a message during our “check” target.
