Question 1

How do I install CMake++ without using the console script?

Accepted Answer

You can download a release file from GitHub and include it manually in your CMake scripts, as described in the 'Install by Downloading a Release' section. This method avoids aliases but requires manual file management and inclusion in each script.

Question 2

Is CMake++ compatible with older CMake versions?

Accepted Answer

It works with CMake >=2.8.12, but some functions might fail with older versions. The README explicitly states that full functionality is ensured only with newer versions, so upgrading is recommended for reliability.

Question 3

How can I use CMake++ to fetch dependencies during a build?

Accepted Answer

Use the package management functions in the dependency management section, such as those demonstrated in samples like 'Compiling a simple program by including cmakepp and pulling eigen library'. These allow direct HTTP fetching and installation within scripts.

Question 4

CMake++ vs using plain CMake with ExternalProject_Add for dependencies?

Accepted Answer

CMake++ offers more integrated features like maps and HTTP client for expressive scripting, while ExternalProject_Add is more basic and CMake-native. CMake++ simplifies complex dependency graphs but adds overhead and learning curve compared to vanilla approaches.

Question 5

What are common pitfalls with CMake++'s return value pattern?

Accepted Answer

The return() function can cause string escaping issues, and return values should be consumed immediately to avoid reuse. The README's 'Returning values' section details these caveats and suggests using return_ref for references to mitigate problems.

Question 6

Can I use CMake++ for web requests in build scripts?

Accepted Answer

Yes, it includes an HTTP client module for making GET and other requests, as shown in the web section and CLI examples. You can fetch data, parse URIs, and integrate web APIs directly into your CMake build logic.
