Scott K Logan a3b35a2aa4 Fix some unreliable STREQUAL calls in CMakeLists.txt 
These conditionals may fail if the variable they're checking isn't
defined at all. Adding quotes makes the comparison against an empty
string in this case, which avoids the syntax error.

# resulting binaries still have the RPATH information. This is fine because
# CMake will strip the build RPATH information in the install step.

# Conan's default approach is to use the "imports" feature, which copies
# all the dependencies into the bin directory. Of course, this doesn't work
# quite that well for libraries generated in this Project (see Conan
