如何从CMake中删除所有默认编译器选项

Question

我正在尝试使用一个非常不寻常的编译器(CC65)来使用CMake，以便在我的项目中使用CLion。

我已经让CMake调用了正确的编译器，但是CMake仍然添加了我不需要的各种GNU编译器选项：

    Compiler exited with error code 1: /opt/local/bin/cc65 -xc -g -D DEBUG --asm-define DEBUG -t atari -fpch-preprocess -v -dD -E
    cc65: Unknown option: -xc -g -D DEBUG --asm-define DEBUG -t atari -fpch-preprocess -v -dD -E -D___CIDR_DEFINITIONS_END

如何摆脱所有的默认选项，以便我可以从头开始，逐步建立正确的选项？

更新1:

使用的工具链文件不是由我开发的，而是简单的：

cmake/blob/master/toolchain/cc65-toolchain.cmake

更新2:

我不会亲自打电话给CMake文件。我只努力使用JetBrains CLion。如果不是CLion的话，我只会使用GNU。

因为我自己不把CMake称为命令行选项，所以我使用set()函数。

set (CMAKE_TOOLCHAIN_FILE "${PROJECT_SOURCE_DIR}/Library/CMake/Atari/cc65-toolchain.cmake")

全部产出如下：

更新3:

为了确保我检查了是否可以调整CLion生成的命令。我是成功的，输出略有不同，但净结果保持不变：

更新4:

切换到CLion的默认工具链配置，以查看这两个工具链之间是否存在冲突。但这会导致所有选项都被传递为“DOS样式”，而不是“/”，而不是“-”。

Answer 1

在CMake论坛的一些帮助下，(剩下的)问题已经被定位为(很可能)在CLion中。现在在使用终端时创建生成文件：

>cmake --toolchain Library/cc65-toolchain.cmake -S . -B cmake-build-release 
-- The ASM compiler identification is cc65
-- Found assembler: /opt/local/bin/cl65
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - failed
-- Check for working C compiler: /opt/local/bin/cl65
-- Check for working C compiler: /opt/local/bin/cl65 - works
-- Warning: Did not find file Compiler/cc65-ASM
> CMAKE_ASM_COMPILER:  /opt/local/bin/cl65
> CMAKE_C_COMPILER:    /opt/local/bin/cl65
> CMAKE_AR:            /opt/local/bin/ar65
-- Configuring done
-- Generating done
-- Build files have been written to: /Users/Shared/Work/Projects/6502Tutorial/Atari/cmake-build-release

当然，我曾经尝试从终端上打电话给CMake，在它没有工作的时候也是如此。

我的猜测是，有多个问题，其中一些是我修复的，现在剩下的所有问题都是关于CLion的。因此，原来的问题已得到答复：

CMake默认选项可以通过使用适当的工具链文件.删除。

感谢所有帮助解决这个棘手问题的人。我会打开一个在JetBrains论坛上的后续文章。
