Fix build with googletest >= 1.8.0-9 that moved header files around

Looks good. Since you are building the Google mock lib from source, you will not need a build dep on libgmock-dev nor on libgtest-dev. The googletest dep is enough.

Doesn't seem true here.

I don't know if whatever flightcrew it's doing is regular or not, but removing the libgmock-dev and libgtest-dev leads to:

/build/flightcrew-0.7.2+dfsg/src/FlightCrew/tests/stdafx_tests.h:22:10: fatal error: gtest/gtest.h: No such file or directory
 #include <gtest/gtest.h>
          ^~~~~~~~~~~~~~~
compilation terminated.

If you have any clue on how to improve the situation, you are more than welcome to commit whatever you want and team upload it :)

I committed a fix -- see 763c0ece. However, IMHO, it's not important enough for an immediate upload.

Ack, thank you!
