ROOTTEST_COMPILE_MACRO: fix default_root_include_path

[andresailer]

Similar to what was observed here: #19179 (comment)

Quotes are escaped or somehow treated differently by cmake, making the ROOT_INCLUDE_PATH not work, dropping the quotes makes the test pass. Paths with spaces are not supported for some time

Related: paths with spaces are no longer supported, as was said here #20098 (comment)

Support for spaces was already discontinued, see #19795 And #20054

LGTM.

I guess you need this backported to 6.38.02, @andresailer?

[andresailer]

Hi @guitargeek

We would need this in the 6.38 branch for running tests. But we don't need this for a release.

[guitargeek]

Okay! It's staged for the backport:

• [v638] Backport recent fixes #20741
