如何将CMAKE生成的Makefile与Echo编译器的命令线进行？
在Linux上，我可以使用CMAKE构建一个C ++项目，例如：
$ mkdir build
$ cd build
$ cmake ../myproject
$ make
[ ] Building CXX object ...
是否有一种方法可以通过选项进行CMAKE或制造，以便它将打印完整的命令线（以及所有选项），它传递给C ++编译器以编译每个命令。对象文件？
（我尝试过：
$ make V=1
但是它似乎不起作用。我猜Cmake生成的Makefile不能适合该选项吗？）
On Linux I can build a C++ project with cmake like:
$ mkdir build
$ cd build
$ cmake ../myproject
$ make
[ ] Building CXX object ...
Is there a way to pass an option to cmake or make so that it will print the full command-lines (and all the options) it is passing to the C++ compiler to compile each object file?
(I tried:
$ make V=1
but it doesn't seem to work. I guess the cmake-generated Makefile doesn't work with that option?)

按照此链接有三个选择（在HolyblackCat的答案中找到+1额外）：
1
如果您可以 /要修改
cmakelists.txt < / code>，您只需添加这必须在您的项目中的每个中完成每个 cmakelists.txt文件，因此，如果您想为整个项目启用它，可能会有些麻烦。
2
要将详细的更改直接更改为makefile，您可以运行CMAKE命令，该命令使用附加标志生成Make File：
并且您猜对了，要将其禁用，您需要再次运行它：
3
最后，如果您构建构建您的项目通过调用
制作，并且不使用cmake -build ./path或cmake -build -build ./ path -target target命令，您可以将其作为选项直接传递给make：尽管我不推荐它，因为它们的整个cmake的目的是不必再使用Make（尽管它仍然在幕后被调用） 。
As per this link There are three options (+1 extra found in the answer of HolyBlackCat):
1
If you can / want to modify the
CMakeLists.txt, you can just addThis has to be done in every CMakeLists.txt file in your project though, so it might be a bit cumbersome, if you want to enable it for the entire project.
2
To write the verbose changes directly to the makefile, you can run the cmake command which generates the make file with an additional flag:
And, you guessed it, to disable it, you need to run it again:
3
Finally, if you build your project by calling
makeand do not use thecmake --build ./pathorcmake --build ./path --target targetcommands, you can pass it as an option tomakedirectly:Although I would not recommend it, because they whole point of cmake is to not have to use make anymore (although it's still called behind the scenes).
使用
make verbose = 1或cmake -build＆lt; path＆gt; - Verbose自动调用使用的生成器的正确命令。Use either
make VERBOSE=1, orcmake --build <path> --verbosewhich automatically invokes the right command for the generator you used.
