我将旧样式的 makefile 转换为 CMake CMakeLists.txt 文件，以便可以将项目加载到 JetBrain 的新 CLion IDE 中。
我认为这很容易，但我被困在 CMake 将一些自定义编译器标志附加到导致编译错误的编译命令上。我没有足够的 CMake 知识来解决这个问题。
这是原始的makefile。

HDRS = $(HDR1) $(HDR2) $(HDR3)

# Full compile and link

$(CC) $(CFLAGS) -o $(ELF1) $(SRCS)
clean ::
del *.dump
del *.elf
del *.bin
这是我对 CMakeLists.txt 文件的尝试。

这是生成的编译命令：
C:\GNUHC11\bin\m6811-elf-gcc.exe "-xc" "-Dmc6811" "-Os" "-Wl,-m,m68hc11elfb" "-mshort" "TestProgram.c" "Interrupts.c" "Utilities.c" "-IC:\\DEVELO~1\\source" "-IC:\\library\\gel-hc1x-1.6.1\\include" "-IC:\\library\\gel-hc1x-1.6.1\\include\\asm-m68hc11\\arch-32k" "-v" "-dD" "-E" "-D___CIDR_IGNORE_DEFINITIONS_START"
它可以工作，但最后自动附加的“-E”编译器标志是我不想要的。其他附加标志“-v”“-dD”和“-D___CIDR ...”也是不需要的，但不会像“-E”那样导致编译错误。如何关闭这些附加标志？
提前感谢您的帮助。
