[Lldb-commits] [lldb] [lldb] Allow specific 'make' tool for LLDB testsuite. (PR #93367)

https://github.com/vvereschaka created https://github.com/llvm/llvm-project/pull/93367

Because the 'make' tool is required to run the lldb testsuite a detection of this program was added to the CMake script. If 'make' tool is missed on the host CMake raises a fatal error now.

It is possible to provide a full path to the 'make' tool via 'Make_EXECUTABLE' CMake variable through the command line:

```
  cmake -DMake_EXECUTABLE=c:\path\to\make.exe ...
```

The found tool gets passed into the lldb testsuite scripts using a newly added argument --make. This option also can be used directly via LLDB_TEST_USER_ARGS CMake configuraion parameter:

```
  cmake ...
    -DLLDB_TEST_USER_ARGS="...;--make;C:\\Path\\to\\make.exe;..."
    ...
```

These options are useful on the Windows build hosts.

Subject: [PATCH] [lldb] Allow specific 'make' tool for LLDB testsuite.

Because the 'make' tool is required to run the lldb testsuite a detection of this
program was added to the CMake script. If 'make' tool is missed on the host
CMake raises a fatal error now.

It is possible to provide a full path to the 'make' tool via 'Make_EXECUTABLE'
CMake variable through the command line:

```
  cmake -DMake_EXECUTABLE=c:\path\to\make.exe ...
```

The found tool gets passed into the lldb testsuite scripts using a newly added
argument --make. This option also can be used directly via LLDB_TEST_USER_ARGS
CMake configuraion parameter:

```
  cmake ...
    -DLLDB_TEST_USER_ARGS="...;--make;C:\\Path\\to\\make.exe;..."
    ...
```

These options are useful on the Windows build hosts.
