bazel notes:
Compile bazel is based on the work area, which is the root directory of the project
1. workspace file: the development of the current folder is a bazel workspace.
2. One or more build files, if a directory workspace contains the build file, then he is a package. Therefore, to develop a directory of bazel workspace, you simply create an empty workspace in the directory that is can.
//: file under the symbol identifies the root directory
target：
cc_binary (name)
cc_libary
cc_test
Visualization:
bazel query --nohost_deps --noimplicit_deps 'deps(//main:hello-world)' --output graph
bazel There are two key elements, a Package is, the other is a target package are independently compiled project packet, identified by the document workspace (which may be empty); BUILD target file is a key element, which is compiled object, the target can be a binary file (cc_binary), may be libary (cc_libary)
Additional options:
visiblity: ["//visibility:public"],['//visibility:private'](私有)，['//some/package:__pkg__'](注意冒号) ex: package(default_visibility = ["//visibility:public"])
