1. Make sure that cudart-7.5.pc is in a directory in PKG_CONFIG_PATH
2. Make sure the contents of that file point to where the actual
libraries/headers are.  The packages from nvidia contain the original
build directory paths which will never work when installed on a system.
3. Optionally, there's the --with-cuda-prefix argument which will check
for the libraries/headers manually.
4. If all else fails, You can override CUDA_CFLAGS and CUDA_LIBS
manually.  This should only be a last resort.

You can check
https://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/configure.ac#n1901
for the logic of what's used when.
