Getting Started: Which GCC should we compile using CMAKE with to avoid failing due to warnings? #20
Description
Since some of the GCC versions will throw warnings and cause the build to fail, which compiler should I use to compile the library?
Note for my use case I will still need to compile my own client code that will use this library with C++20, but I am wondering what GCC I should use to compile this driver with?
For example: GCC GNU 11.2.1 throws the following error
[warrenniles@localhost build]$ cmake ..
CMake Warning (dev) in CMakeLists.txt:
No project() command is present. The top-level CMakeLists.txt file must
contain a literal, direct call to the project() command. Add a line of
code such as
project(ProjectName)
near the top of the file, but after cmake_minimum_required().
CMake is pretending there is a "project(Project)" command on the first
line.
This warning is for project developers. Use -Wno-dev to suppress it.
