Visual Studio Projects

IDE used: Microsoft Visual Studio Community 2019

CMake Projects

CMake and Platforms

Window

• Generate Visual Studio project files: cmake -G "Visual Studio 17 2022" . // cmake -S . -B build/
• Build the project: cmake --build .

Linux

Tools used:

cmake version: 3.22.1
make version: GNU Make 4.3
C compiler: GNU 11.4.0

CMake commands

• Go to project root directory: cd <path-to-root-directory>
• Generate build files:
  • Generate build files with detecting tools automatically: cmake -B build (same as mkdir build && cd build && cmake ..)
  • Generate build files with flags: cmake -S . -B build -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++
    • -S .: source directory (current directory)
    • -B build: build directory (build)
    • -G "Unix Makefiles": select generator (Makefile)
    • -DCMAKE_BUILD_TYPE=Debug: select build type
    • -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++: force specific compiler
• Build project:
  • Build project: cmake --build build or cd build && make
  • Make + Install: cmake --build build --target install
  • Clean before build: cmake --build build --clean-first
• Run executable: /build/<app-name>.exe
• Clean/Remove build directory: rm -rf build/

Some helping commands

• ldd /build/<app-name>.exe: LDD: List Dynamic Dependecies (shows all shared library dependencies of an executable)

Debugs / Errors

'cmake ..' not working in linux -> '-- Check for working C compiler: /usr/bin/cc - broken'

-> sudo apt-get install build-essential
