Makefile with specific dir, which is NOT avaliable

[lida2003]

/opt/vc/include/, /usr/include/freetype2 is a specific dir. Is it possible to use code in git or any pre-configuration or setup procedure can hanle these specific dirs?

INCLUDE  := -Isrc \
    -Isrc/utils \
    -Isrc/imgui \
    -Icomponents/common \
    -I/opt/vc/include/ \
    -I/usr/include/freetype2

I tried raspberry pi3 build as docs suggested, it failed. And I checked Makefile it includes crc folder. Any idea?

The above patch can solve compilation on RPI 3b+.

Hope the code can be compiled on laptop (ubuntu)

[lida2003]

OK. I see the PR is accepted.
