invalid cmake target while building

[ybiao-he]

Hi,

I met the following error when I build using scripts/build.py -o release

I wonder where the problem is, should I change the build setting? and what setting I should use if changes are needed. Thanks.

@ybiao-he Hi, i meet the same error here, did you find the solution? Thanks!

Sry for the late reply. It should be an issue related to your cmake version. You can either try another cmake version or remove the --target argument in scripts/build.py.

I think the reason is that there is an error in the provided command (or I am unable to find the correct usage method). The original cmake command is "cmake --build build --target -- -j 6". Therefore, I used the command "scripts/build.py -o release -t iccad19gr" to assign a value to the "target" parameter, then the cmake command(in python file) change to "cmake --build build --target iccad19gr -- -j 6", it worked!

@Mrsun0 说得对，问题出在：
https://github.com/cuhk-eda/cu-gr/blob/dac2020/scripts/build.py#L49

elif args.targets is None:
    build_targets = ['']

导致在

cu-gr/scripts/build.py

Line 59 in 9b1aa8a

for target in build_targets:

的循环里面展开出空字符串。
