网上有很多例子是基于ninja的bug。排除ninja的问题后还有错误：

带上explain参数能显示具体的错误：

1 2 3 4 5 6 7 8 9 10 11 |
C:\open-enclave.0.8.1\openenclave\share\openenclave\samples\switchless\build>ninja -d explain ninja explain: output build.ninja older than most recent input ../CMakeLists.txt (603082958 vs 603092436) VERBOSE-- Looking for sgx_enclave_common library - found VERBOSE-- Looking for sgx_dcap_ql library - found -- Configuring done -- Generating done -- Build files have been written to: C:/open-enclave.0.8.1/openenclave/share/openenclave/samples/switchless/build ninja explain: output build.ninja older than most recent input ../CMakeLists.txt (603082963 vs 603092436) ......

查看一下文件时间，Modify time还在未来：

修改文件时间到过去或者把系统时间设在将来，错误消失了。
关于Jenkins上用cpack打包时怎么会把文件时间设在未来，待续。
