[CMakeFiles/Makefile2:1680: VINS-Fusion/vins_estimator/CMakeFiles/vins_lib.dir/all] Error 2

This error message indicates that there was an error while building the "vins_lib" target in the "vins_estimator" subdirectory of the "VINS-Fusion" project. The specific error that occurred is not provided in the message, so you will need to look further up in the build output to see the actual error message that caused the build to fail. Once you have identified the cause of the error, you can take steps to fix it and try building again. Some common causes of build errors include missing dependencies, incorrect compiler options, and syntax errors in the code.

CMakeFiles/Makefile2:136: recipe for target 'CMakeFiles/plslam.dir/all' failed

CMakeFiles/Makefile2:136: recipe for target 'CMakeFiles/plslam.dir/all' failed是指在构建项目时，发生了错误。具体错误原因可能是代码中的某个部分存在错误，或者缺少某些依赖项。要解决这个问题，你可以尝试以下几个步骤:

1. 检查代码中是否存在语法错误或其他错误。特别注意与目标'CMakeFiles/plslam.dir/all'相关的代码部分。

2. 检查是否缺少必需的依赖项。在构建过程中，确保所有依赖项都正确安装，并且与项目的版本兼容。

3. 确保你正在使用正确的构建工具和编译器。检查你的环境设置，并确保使用适当的版本和配置。

4. 清理构建目录并重新构建项目。有时，构建过程中的文件冲突或缓存问题可能导致错误。可以尝试删除构建目录并重新构建项目。

make[2]: *** [CMakeFiles/PhotonEvaporation.dir/build.make:98: Externals/PhotonEvaporation-5.7/src/PhotonEvaporation-stamp/PhotonEvaporation-download] Error 1 make[1]: *** [CMakeFiles/Makefile2:959: CMakeFiles/PhotonEvaporation.dir/all] Error 2

这段引用内容看起来是关于编译错误的信息，具体是关于一个名为PhotonEvaporation的项目的编译错误。根据引用内容中的错误信息，可以看出在编译过程中出现了两个错误。第一个错误是在构建文件`CMakeFiles/PhotonEvaporation.dir/build.make`的第98行，导致了`PhotonEvaporation-download`的构建失败。第二个错误是在构建文件`CMakeFiles/Makefile2`的第959行，导致了`CMakeFiles/PhotonEvaporation.dir/all`的构建失败。这些错误可能是由于编译过程中的某些问题导致的，可能需要检查编译环境、依赖项或代码本身来解决这些错误。
