}Copy the contents of the src directory to a project directory which is under
an include path of a compiler, for example, src/3rdparty/dmitigr.
Create hello.cpp:
#include "dmitigr/fcgi/fcgi.hpp"
int main()
{
// Application code here...
}Compile hello.cpp:
g++ -std=c++17 -ohello hello.cpp
Create build directory, configure, build and install:
cd fcgi
mkdir build && cd build
cmake ..
cmake --build .
sudo cmake --install .
Create hello/hello.cpp:
#include "dmitigr/fcgi/fcgi.hpp"
int main()
{
// Application code here...
}Create hello/CMakeLists.txt:
cmake_minimum_required(VERSION 3.16)
project(foo)
find_package(dmitigr_cpplipa REQUIRED COMPONENTS fcgi)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
add_executable(hello hello.cpp)
target_link_libraries(hello dmitigr_fcgi)Compile hello/hello.cpp:
mkdir hello/build && cd hello/build
cmake ..
cmake --build .
