What are some tips for optimizing CMake builds?

To optimize CMake builds, consider using the following tips: 1. Use the CMAKE_BUILD_TYPE to specify the build type. 2. Enable parallel builds with -j option. 3. Use CMAKE_CXX_FLAGS to set optimization flags like -O2 or -O3. 4. Minimize unnecessary dependencies. 5. Use find_package wisely to avoid redundant searches.

How can I reduce build time in CMake?

You can reduce build time by enabling incremental builds, using precompiled headers, and avoiding unnecessary recompilation by organizing your code into smaller modules.

What are precompiled headers and how do they help?

Precompiled headers are a way to compile common headers once and reuse them across multiple source files, significantly reducing compilation time.

Can I use CMake with multiple platforms?

Yes, CMake is designed to be cross-platform. You can write platform-independent CMake scripts and use them to generate build files for different platforms.
