Raspberry pi 3 compile issue & how to run examples

[wangbaishi]

Raspberry pi 3 model B+, OS version: Debian 11 (bullseye)
When compiling on raspberry pi I got compile error:
glcontext_egl.cpp
../../../src/glcontext_egl.cpp:155:9: error: ‘EGL_DISPMANX_WINDOW_T’ does not name a type
155 | static EGL_DISPMANX_WINDOW_T s_dispmanWindow;
After digging around I found this thread: https://forums.raspberrypi.com/viewtopic.php?t=252978
It seems that some PI specific code in glcontext_egl.cpp is no longer needed... I was able to compile bgfx successfully after modify glcontext_egl.cpp and now I want to run example code to check the modification is good, but I can't find the location of the executables. It seems that examples didn't get compiled according to console output. How can I compile the examples?
