Ah, I misunderstood the question. I think this is a general compilation/linking performance question; I've used gtest in other projects and by itself it's been fast when rebuilding unittests (that is, re-linking against the gtest library already built).

I don't know how you have the code setup, and I don't know what you've tried, but I would look at the following:
* Determining if the overhead is in compilation or linking
* Splitting the testsuites into separate .cpp's
* Building as Debug (-O0)

I've only done minimal development within Inkscape, I'm curious: are the tests you wrote within it or a standalone project?

@Mark Exactly, but that is only the "run" part in my question
concerning _building_ the tests and running them. The main problem is
that the build time is too long when building all the tests into one
giant test executable. So I can rephrase my question:

Has anyone used Google Test and succesfully created a structure of
test suites and cases to be able to build only a single test suites or
a few test cases when needed?

Of course, before committing the changes all tests must be run at
least once, but during development you only want to iterate over a
single test suite/case you're focusing on at the moment.
