-It's easy to use cmake official [docs](https://cmake.org/cmake/help/git-stage/module/FindPython2.html#module:FindPython2) to find Python 2(or 3) interpreter, compiler and development environment (include directories and libraries).
+To compile the code without using cmake, the compiler invocation should look like
+this:
 
-NumPy is optional here, delete it from cmake script, if you don't need it.
+    g++ example.cpp -I/usr/include/python2.7 -lpython2.7
 
-```cmake
-find_package(Python2 COMPONENTS Development NumPy)
-target_include_directories(myproject PRIVATE ${Python2_INCLUDE_DIRS} ${Python2_NumPy_INCLUDE_DIRS})
-target_link_libraries(myproject Python2::Python Python2::NumPy)
