The list contains all manuals for which help may be obtained by Then do the final compile with Android Studio which uses Gradle to call CMake to compile the project.

Ah, thanks for the prior context - sorry I missed that review. Download and install CodeIt.Right, which will then be your second line of defense against all kinds of mistakes and bad practices that threaten your project’s health. In modern CMake, the following works well: if(MSVC) So we are left with this: if (MSVC) string (REGEX REPLACE "/W [1-3]" "/W4" CMAKE_CXX_FLAGS "$ {CMAKE_CXX_FLAGS}") else () add_compile_options (-Wall -Wextra -pedantic -Werror) endif () So is this how it is done in “modern” CMake? If you dont have time, and can ignore “warnings” for a while, just search the code as, grep -r Werror * to identify which Makefile is enabling “Werror” 3. remove/delete this completely from that Makefile or Change it to “-wno-error” 4. save this makefile and recompile the code.

Optimize for size, even if the CMAKE_BUILD_TYPE is not MinSizeRel. If the directory doesn't already exist CMake will make it.
