Thanks for the PR, will raise the issue internally (since this branch is not yet accepting changes directly via github). |

Full ignore the QCOM_COMMON_LICENSE_DIR can be problematic, we should just ignore what is not relevant in this case.
Can you please try this patch:

…LIC_FILES_CHKSUM
Since TOPDIR is appended to the LAYERDIR path contained in this variable,
building from a different directory reduces the sstate-cache hit rate for recipes that use QCOM_COMMON_LICENSE_DIR.
```

basehash changed from 9990fb107900393658bf819b17528ee4810cefe6d09660e6320eccc4e119dac0 to 327c12e7c95192e2d172d7022c2bdbadd292b5a687b0acc1ab939f19c2f7d216
Variable QCOM_COMMON_LICENSE_DIR value changed from '${@os.path.normpath("TOPDIR1/meta-qcom/meta-qcom-hwe")+'/files/common-licenses/'}' to '${@os.path.normpath("TOPDIR2/meta-qcom/meta-qcom-hwe")+'/files/common-licenses/'}'
```
```
List of dependencies for variable LIC_FILES_CHKSUM is ['LICENSE', 'QCOM_COMMON_LICENSE_DIR']
List of dependencies for variable QCOM_COMMON_LICENSE_DIR is []
Variable LIC_FILES_CHKSUM value is file://${QCOM_COMMON_LICENSE_DIR}${LICENSE};md5=58d50a3d36f27f1a1e6089308a49b403
Variable QCOM_COMMON_LICENSE_DIR value is ${@os.path.normpath("TOPDIR1/meta-qcom/meta-qcom-hwe")+'/files/common-licenses/'}
```
The recipe directly depends on `LIC_FILES_CHKSUM`, and `LIC_FILES_CHKSUM` references `QCOM_COMMON_DIR`.
Therefore, excluding `QCOM_COMMON_LICENSE_DIR` from the hash value calculation in `LIC_FILES_CHKSUM` would ideally work.

Adding just the QCOMHWEBASE is what we need given that it is what can vary. |
