The makefile used in the test uses $(shell ...), which is
AFAIK a GNU extension, and will probably not work e.g. with OpenBSD make.
According to the FreeBSD make manpage their make has a != assignment,
which seems to do something similar, but I don't have such a system
around for testing.
Also, the point of this test is not to write a portable makefile,
but to check whether cmake --find-package prints a correct string.

The commit message for the previous commit was wrong, it should
have been: fix the test by using $(shell ...) syntax instead
of backticks in the Makefile.
With backticks I couldn't get the quoting right.
Printing -I"/some/path with space" did not work, the compiler
complained that there is not file "with". Also backslashes in
different numbers did not make it work.

Instead of relying on that some development package is installed on the
system, now a tiny library is built, which is the searched and used
during the test.

BSD make doesn't seem to support -C, so do not use it,
According to the documentation the working directory is set
to CMAKE_CURRENT_BINARY_DIR anyway, so it should work just the same.
