Where are package libraries and header files installed?
After downloading and installing a package on Ubuntu, how can I check where the library and header files were written? I believe it has something to do with the .pc batch file, but I don't know how to find that file.
For example, I downloaded the PCL (Point Cloud Library) package and then in the sample CMakeLists.txt file I was presented with the following:
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
Where are these environment variables defined and how can I see them?
If I compiled the libraries from source and not through a package, would that be any different? Will a .pc file be automatically generated?

If you are installing a package containing libpcl development files
sudo apt-get install libpcl-dev
You can specify installed files
dpkg -L libpcl-dev
a see the location of all headers.

By default, libraries are installed in / usr / lib and header files will be in / usr / include
Usually the extension of the library file is .so and the corresponding header file will be .h
The gui method for finding installed libraries is open software center -> Developer Tools -> Libraries
