Fix search path error for TurboJPEG #31

Closed superdan-t closed 2 years ago

superdan-t commented 2 years ago

The value of ENV{PKG_CONFIG_PATH} was not correctly copied from PKG_TURBOJPEG_PATH before searching for the package. This quick fix fixes that problem so the default path is used.

Fixed some other issues:

Some CMakeLists.txt files did not specify minimum C++ version (rover_can still doesn't)
TurboJPEG always uses unsigned long for size, which is incompatible with size_t on 32-bit systems. Where applicable, the video computer now uses unsigned long

The default TurboJPEG path set in the CMake file is only required if installed manually. Apt can also be used (sudo apt install libturbojpeg0-dev) and pkg-config will find the package without setting the path.
