Ubuntu21.04编译OpenPGP

先安装第三方依赖库

mkdir build
cd build
cmake ..
make
make install

修改CMakeLists.txt
注释以下内容：

If (0)
set(BUILD_TESTS ON CACHE BOOL "Build tests")
if (BUILD_TESTS)
    # create the test target
    enable_testing()

    # add tests
    add_subdirectory(tests)
endif()


set(BUILD_CLI ON CACHE BOOL "Build CLI example")
if (BUILD_CLI)
    # add cli
    add_subdirectory(cli)
endif()
endif()
