 Learn from

Here

Examples - use default modules

ALSA library

You can install the library first.

$ sudo apt-get install libasound2

You can put the following code into CMakeLists.txt.

# Handle ALSA / ASound libraries
find_package(ALSA)
if (ALSA_FOUND)
  message (STATUS "Info - Found ALSA library: ${ALSA_LIBRARY}")
  message (STATUS "Info - Found ALSA include: ${ALSA_INCLUDE_DIR}")
else (ALSA_FOUND)
  message (FATAL_ERROR "Info - ALSA is not found")
endif (ALSA_FOUND)

How can I know which variables I can use?

• Go to official web site 001 or official web site 002
  
• In ubuntu you can go to the installation path and find all the modules
  
• /usr/share/cmake-3.16/Modules
• FindALSA.cmake
