# FindLibP11
#
# Generates an imported target associated to an available pksc11 library:
#
# + On linux relies on the apt package libp11-dev
#
# + On Windows the library must be build from sources available at https://github.com/OpenSC/libp11.git
# Given that each user must build its own binaries the following environment variables must be set to hint
# where to locate headers and binaries (semicolon-separated list see https://cmake.org/cmake/help/v3.22/variable/PackageName_ROOT.html):
# + LibP11_ROOT_32 -> to reference sources and 32 bit binaries location
# + LibP11_ROOT_64 -> to reference sources and 64 bit binaries location
